Loan Reservation Process

All CalHFA approved lenders have access to reserve loans through the CalHFA Mortgage Access System (MAS). Each lender has assigned an MAS Administrator within their own company to manage their employees’ access to MAS. Lenders may have different processes for assigning CalHFA log-ins, passwords, and the reserving of CalHFA loans.

Reservations with a floating rate will be accepted from 6:00 a.m. to 11:59 p.m. Pacific Time, seven days a week. Lenders must reserve loans, including all CalHFA subordinate loans, using CalHFA Mortgage Access System (MAS) prior to loan submission.

Reservations may be made after a sales contract has been executed between the buyer and seller. Approved CalHFA Lenders may reserve funds on behalf of their correspondent lenders or mortgage brokers. All loans must be reserved thru MAS by the approved lender.

For more detailed information, please review the FAQs below, or you may contact CalHFA's Secondary Marketing Unit at:

Duplicate Loans

Borrowers may only have one active CalHFA reservation at any time and the loan may be placed in a possible duplicate reservation status 110 if the borrower currently has/had a CalHFA loan reservation. Loans placed in a 110 status may still be rate locked; however, no loan documents can be uploaded. Please contact CalHFA’s Secondary Marketing Unit at ratelocks@calhfa.ca.gov with the CalHFA loan id and borrower name. All status 110 reservations will be cleared within 24 hours.

Rate Lock Process

First mortgage rate locks will only be accepted between the hours of 8:00 a.m. and 3:00 p.m. PT Monday through Friday, excluding state-recognized holidays, and days that the U.S. financial markets are closed for business.

At the time of reservation the lender will have the option to lock or float the interest rate. Only lenders with full MAS access may lock the interest rate. If loan is reserved with the float option, the reservation period is 90 days on existing/resale properties, or 120 days on new construction properties.

  • At the time of rate lock, the lender will lock the loan(s) for sixty (60) days for both existing/resale properties and new construction properties.
  • For float option only:
    • Lenders may lock the rate at any time during the reservation period if they choose the float option.
    • To lock the rate when the float option is chosen, lenders must complete the Rate Lock in MAS. To help you with the rate lock process please see Guide: Locking a Rate
      • Rate Locks will only be available for loans at a status 120 (New Reservation) through 440 (Notice of Commitment)
    • Rate lock expiration date will supersede the reservation expiration date.
  • All loans must be funded, delivered and purchased by CalHFA’s master servicer, prior to rate lock expiration.
  • Files should be received by the master servicer by the 45th day or earlier, to ensure time to clear conditions and purchase prior to rate lock expiration
  • If the rate lock is cancelled for any reason – lender may not re-reserve/rate lock a new loan for the same borrower and property until sixty (60) days from the current cancelled loan's expiration date.

CalHFA subordinate loans reserved with a CalHFA first mortgage

  • All subordinate loan(s) will receive the same reservation, lock and purchase periods as the CalHFA first mortgage. All subordinate loans must be delivered and purchased by CalHFA prior to the rate lock expiration. 
  • Subordinate loans should be submitted to CalHFA at the same time the first mortgage is submitted to the master servicer to ensure time to clear conditions and purchase prior to rate lock expiration.
